Threadgill stated, "I remember one of my close friends and I used to make a game of seeing who could write a song fastest.
In 2006, Threadgill was a featured player in a documentary film starring Youssou N'Dour, entitled Retour à Gorée and directed by Pierre-Yves Borgeaud.
[3] After several years of performing and raising her daughter, Threadgill wrote and developed a work based on short stories by authors including Jamaica Kincaid and Bruno Schulz.
The song cycle, entitled Portholes to a Love & Other Short Stories, led to her being granted a 2008 Fellowship in music composition through the New York Foundation for the Arts.
Since then, Threadgill has explored other musical-based interests including work with the pianist Marc Cary, as well as theater projects.
